Bomb and arson attacks last Thursday and Friday in the resort town of Hua Hin, Surat Thani, Phuket, Phangnga, Trang, Surat Thani and Nakhon Si Thammarat killed four people and injured 37 others. In Surat Thani, one person died and four were hurt.

Prime Minister Prayut Chan-o-cha on Wednesday conceded there had been slight damage to the country’s image as a tourism destination but expected no slump of visitors.

Tourism Authority of Thailand governor Yuthasak Supasorn has said the attacks could see up to 200,000 visitors cancelling their trips to the country by the end of this year.
